ABSTRACT:
An electronic timepiece which can provide an analog display by a pointer of time information of at least "hour" and "minute" delivered from an electromechanical time keep mechanism and can digitally display by a photoelectric display device a time information set for emitting an alarm and memorized in an alarm memory circuit is disclosed. The electronic timepiece comprises further means for electrically keeping the time information of at least "hour" and "minute", a coincidence detection circuit for detecting a coincidence of the time information delivered from the electrical time keep mechanism with the time information delivered from alarm memory circuit and an alarm emitting device for emitting an alarm signal by a coincidence signal delivered from the coincidence detection circuit.
